The Pink Tower

The Pink Tower is introduced to a 2-1/2 year old shortly after joining the class and consists of 10 wooden pink cubes graded in size (differing in length, breadth and height). The sides of the cubes range from 1cm to 10cm.
The child is shown (by actions, not words) how to build them into a tower on a mat starting with the largest first, then each cube in order of size. The child is then encouraged to build it. The Pink Tower is one of the Sensorial Materials designed by Dr Maria Montessori to help children clarify the sensorial experiences s/he has already had. The materials are designed in such a way that the child's mind is focused on one particular quality. The Pink Tower concentrates on the sense of sight and the concept of size.

These exercises are presented over a period of time as the child’s control of the pencil increases.

‘These drawings perfect a child’s skill in that they oblige him to draw lines of different lengths and make him ever more skillful and sure in the use of this hands… I do not believe that any means could be found more efficacious in gaining such a victory in less time and which could afford so much amusement to a child.
